critical Nessus Plugin ID 91655

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

openssh was updated to fix three security issues.

These security issues were fixed :

- CVE-2016-3115: Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH allowed remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions (bsc#970632).

- CVE-2016-1908: Possible fallback from untrusted to trusted X11 forwarding (bsc#962313).

- CVE-2015-8325: Ignore PAM environment vars when UseLogin=yes (bsc#975865).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
